Answer:

530.66

Step-by-step explanation:

The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14

For this circle we do 3.14 * 13^2

First we have to square 13: 13^2 = 169

Then we multiply 169 by 3.14: 3.14 * 169 = 530.66

Then we do to the nearest hundredth which is the same as the previous answer: 530.66

How do you know where to put the constant when finding general solutions for differential equations?
Norma-Jean [14]
Let's suppose we want to solve y'=y with y(0)=2. Separating variables and integrating, we get

\displaystyle\int\dfrac{\mathrm dy}y=\int\mathrm dx\implies\ln|y|=x+C\implies y=e^{x+C}

Leaving the solution in this form, the initial condition gives

2=e^{0+C}=e^C\implies C=\ln2

This means the solution is y=e^{x+\ln2}.

Now if we were to write y=e^{x+C}=e^xe^C=Ce^x, then we would have found

2=Ce^0\implies C=2

so that the solution would have been y=2e^x.

But these two solutions are the same, since y=e^{x+\ln2}=e^xe^{\ln2}=2e^x. So we get the same solution regardless of where we place C, despite getting different values for C.
